To all whom it 'may concern: Be it known that l, lltzxnv lt. Panam, a eitizen'of the United States. and a residentol the borough of Trappe, in the eounty of lllontgomery and State ot' Pennsylvania,

have invented eertain new :unluset'nly lin` bed, as seon as they are released from the` shells, into asuitable brooder chamber; and for satisfactorily securing uniform heating, effective ventilation: and proper eleanliness, in a simple and inexpensive Construction.

Figure 1 is mainly a frontv elevation of an incubator embodyingr my improvements in preferred form, `eertain portions bein;r broken away to more clearly show the eonstrnetion. Fig. Q is a erosh-seet ion taken on the line 2 of ["ig. l. Fig. ,3 is a `separate perspeetive view ot' the eggdray.

As shown the bed plate l ot' the incubator is a separate. part', upon which the inverted box 2 eonstitutingthe main part. is so placed aS to be readily removed for atording convenient aecess to the bed for cleaning; the requisite tightness of the inelosure being secured by providing a suitable depressed seat 3 of rubber or other material upon whieh thek edge of they inverted bex rests. The double walls of the latter are provided to better retain the heat, as usual, and are also arranged, as Shown, to seat upor the edges of the brooder eashion l whieh is plat-edi upon the bed-plate and upon whieh the new born ehielts are dropped trom the egg-tray .as hereafter deseribed.

'lln-v heat-radiatingr meanl provided enne prises as Shown a water pan lt) lot'aled below the top 11 and extra-.dingr between thtv laide walls 1:! and lil ofthe box: ilrear end bein;lr provided with a depending delleetor plate ll spared apart from the real' wall l."

A vertical partition :il forms a closed air chamber for the dependingboiler attachment 20; and upon the inner face of this-partiion and of .thefopposite box well are provided Shelves l 25, 25, upon whirh the egg r'ay 30, introslidablv supported between the heating pan l() and the brooder bed-plate. The egg tray 30. as A hown. eou i-3t z ot" a reetangular frame in 'which are .Lrured a series of rods 3l, 3l. forming agri-ated bed; the rods being spaced.

rod and au :uljaeent'oue, the arranpeinentl beinet adapted not only to Safely retain the eggs upon the tray during the period of ineubation, but. also to relea5 e the new born ehielts and :uttontatieally deliver them tothe brutaler' bed beneath. Moieover each of the e parallel rods 3l, as shown, is rotatabl v mountedin the tray fraaie, and theyY are so reared together as to enable the operator toisimultaneously turn the whole Series of rods in one direction and thereby exert an i ell'eeliw turning;r aetion upon eaelt and every egg; mipported between the rods; the projet-ting end of eaeh rod being provided with f a lixed bevel gear 33. whieh arranged in meuh with one of a Series of Similar gearS :tI- fixed to a tranwerse operating shaft 34;

tray: and the end of) of aid l l1att being;` adapted for engagement bhv a mutable opteratiun lever iusertible tln'mzgh a covered hole t it! the. wall ofthe box.

l 'l`he eggs are placed end-to-end in eaeh snare. between adjaeent rod 3l of the egg tray. eaeh egg being supported upon said rods at opposite points somewhat below (be longitudinal axis of the egg. The upper Y Patented Sept. 27, 1910. i. Application fded May 1G, 39].0. Serial No. 561,532. v

brooder bed beneath, thus freeing the later` developing chicks from contact therewith, and promptly placing the released chiclcs in the wholesome atmosphere of the broeder cli. iiiber. The subsequent cleaning of the brwoder bed is greatly facilitated by simply lifting the incubator box therefrom as provided for.

The -water par. above the egg-tray provides for uniform heating of the eggs, the heated water extending over the entire tray and the quantity of water employed iiisiiriiig against the chilling of the eggs by the accidental burning out or extinguishingr of the lamp, the water retaining its heat for hours after the lamp is out. Butthe` preferred heating means described may obviously-be varied it desired, and the detailed construction otherwise modified without departing from my invention as specifically pointed out in the claims.

What l claim is:-

1. Asn incubator box, heat-radiating means' in the upper portion thereof, and an eggl tray located between said heatradiating means and the bottoni of the box, said box having top air inlet and air outlet openings and connecting passage-ways wherebv the iiitlowing air is circulated upwardly t; .rough the tray Substantially as set forth. 2.
